Guides to browser-based measurement
Each guide takes one measurement question and answers it properly: what is recorded, how the result is calculated, and what a browser can and cannot see. For the procedure of an individual test, the test page itself remains the reference.
Published guides
- How Reaction Time Tests WorkWhat a browser reaction time test actually measures: visual stimulus timing, performance.now(), frame-aligned presentation, false starts, and why display and input latency are part of every number.
- How WPM Is Calculated in a Typing TestThe words-per-minute formula explained: the five-character word convention, why Testpartout counts only correct characters, how the 60-second run and cumulative mistakes work, and a worked example.
- How Click Speed Tests WorkHow Testpartout measures clicks per second: the fixed 10-second session, first pointerdown start, primary pointer rules, deadline handling, local personal bests, and browser limitations.
- How Visual Memory Tests WorkHow Testpartout measures visual memory span with a fixed 6×6 grid, three starting targets, 1.5-second presentation, recall rounds, lives, and browser display limits.
- How Aim and Accuracy Tests WorkHow Testpartout measures aiming accuracy: 30 trials, circular hit detection, hit-only average time, target spacing, input modality, and why speed and accuracy stay separate.
Guides follow the same rules as the rest of the site: they describe the implementation as it exists, and they do not publish averages, rankings or percentiles that no real aggregated data supports. See the editorial policy and methodology.
